Question

我正在尝试运行一个在spark 1.3.1中完美运行的Python spark脚本。我已经下载了spark 1.4并尝试运行脚本，但它一直在贬低

在类路径中找不到Spark Streaming的Kafka库。试试吧   以下。
在spark-submit命令中包含Kafka库及其依赖项
$ bin/spark-submit --packages org.apache.spark:spark-streaming-kafka:1.4.0 ...
从Maven Central http://search.maven.org/下载工件的JAR，Group Id = org.apache.spark，Artifact Id = spark-streaming-kafka-assembly，Version = 1.4.0。然后，将spark包含在spark-submit命令中
$ bin/spark-submit --jars <spark-streaming-kafka-assembly.jar> ...

我在提交命令中明确引用了jar，并将jar添加为

/opt/spark/spark-1.4.0-bin-hadoop2.6/bin/spark-submit --jars spark-streaming_2.10-1.4.0.jar,spark-core_2.10-1.4.0.jar,spark-streaming-kafka-assembly_2.10-1.4.0.jar,kafka_2.10-0.8.2.1.jar,kafka-clients-0.8.2.1.jar,spark-streaming-kafka-assembly_2.10-1.4.0.jar /root/SparkPySQLNew.py

它还说它在应用程序启动时添加了它们，为什么它找不到它们？

而且我知道我已添加了大量的内容，我开始使用其中一个，然后最后将它们全部添加到最后。

Answer 1

我怀疑确切的答案因spark版本不同而异，但是基于this HCC thread，以下似乎可以解决其他问题：

spark-submit --jars spark-assembly-1.5.2.2.3.4.7-4-hadoop2.7.1.2.3.4.7-4.jar,spark-streaming-kafka-assembly_2.10-1.6.1.jar

乍一看，不同之处在于它有1个spark-streaming-kafka-assembly jar，而您要提交两个。

Spark 1.4缺少Kafka库
